Not there yet but working on it. Personally I'm 56 and still riding 3 different bikes, a KLR, 530 KTM and a 990 KTM. I also hope to be riding into my 70's. I think the two biggest things you can do to help the cause are to stay in reasonable shape and keep your expectations reasonable. I now ride for enjoyment, not pride or bravado. Just look at Malcolm Smith, just a few years ago (well past the legal age for Senior Citizen) he showed up at the Pikes Peak Hill Climb on a vintage air cooled 2 stroke Husqvarna and beat 95% of the entrants! My brother who is 66 just got back into the sport after being away for 40 years and is loving his KLR. There are a lot of older riders out there, don't feel alone. I can honestly say motorcycling has been one of the most consistent and joyful aspects of my life, for over 44 years now.
